Abstract
Dispositif émetteur comprenant un émetteur, un circuit indicateur de trajet de transfert occupé, et un circuit de commande présentant une entrée pour un signal de demande d'émission ce circuit de commande étant conçu pour produire, à une sortie qui est couplée à une entrée de commande dudit émetteur, un signal d'activation de transfert pour ledit émetteur en réaction à l'amenée d'un signal de demande d'émission à l'entrée du circuit de commande, caractérisé en ce que le circuit de commande est agencé de manière que ledit intervalle de temps prédéterminé est d'autant plus long que le temps qui s'écoule entre l'amenée dudit signal et l'indication résultante par le circuit indicateur que le trajet de transfert n'est plus complètement occupé, est plus court. Application : systèmes de transfert d'information.
